Kodak wrote it so this is clearly a case for them to answer.It may have evaporated before you get a reply.
please define what's a typical diluition
sure photflo can also be used at 1:infinite LOL
The "Typical" refers to the fact that many of the chemicals on that chart can be used at a variety of dilutions, so the chart indicates which one is referred to.please define what's a typical diluition

exactly;2cc/400ccof water,1+200,1:200,5ml/1l; it's all the same. a drop or two are enough. this thread is over discussed by now. let's move on.LOL its really a couple of drops in a tank / tray of water
and i agree with PE a bottle will last a lifetime, a small bottle
of the old stuff i bought in 1981 just finished about a year or 2 ago.
that said, if someone wants to add 1cc 200 cc of water, i am sure that's fine too/

my experience is similar to yours; far less than 1:200;a drop per500ml is plenty; otherwise, I get watermarks.As indicated by the name, Kodak recommends a dilution for this wetting agent of 1:200. My experience is that I need far less (1+2,000) to avoid water marks, and our water is not very soft either.
How do you dilute Photo-Flo, and what are your experiences with this product?
I think reusing it the same day and otherwise, make fresh is a sensible approach.SEVEN PAGES on PhotoFlo? Egad.
- Photo Flo standard dilution in one in 200 (not 1 plus 199 though it makes no practical difference) Ilford calls this 1+200 Kodak calls is 1:200.
- I use two rinses at the end of 35mm processing since the darn holes trap water, one with plain distilled then one with PhotoFlo and with distilled I find I can use 1+300 or even 1+400. The only squeegee I use are my two fingers, I used to use Photowipes on the back only of 35mm films but PhotoWipes are really tough to find and probably no more when my current stash are gone.
- For 120 etc. I find that just a final dip in PhotoFlo is enough.
- Note that if you use tap water or boiled water you need to test.
- I'm not doing production work and don't save my PhotoFlo to use another day though I might reuse it on the same day.
my experience is similar to yours; far less than 1:200;a drop per500ml is plenty; otherwise, I get watermarks.
I stopped using Photo-Flo years ago and switched to Edwal LFN. Edwal calls for two drop of LFN per one pint of distilled water, and is reusable for quite some time.You can also add one drop of LFN to developer to eliminate bubbles from forming on film during development. IMO, a far superior product to Kodak's.

It's a mere "serfacant" , has nothing to do with wash or development or with dust spotting. It just prevents water from beading up and depositing whatever minerals it happens to hold.
Its a very simple detergent. You could use dishwashing liquid if that didn't have lots of secondary crapola in it, such as perfume.
Dip your film in it after washing..only takes a second.

Perfumes are typically in formulations at 0.03%. I doubt that would do anything to film. They are extremely volatile and evaporate like solvents.
IDK PE says differently, theres all sorts of stuff in dish soap and jet dry ( another favorite for cheapskates ) photoflo costs very little its amazing people waste their efforts on other stuff
( other stuff does not include other photographic products sold as end run, like sprint end run, LFN &c )
i mean even at 200:x &c its still like .001¢ a use ... i guess the problem is that it doesn't soften your hands as you do the dishes, i mean rinse your film ...
Ha &1As you and I have discussed before, we know that PhotoFlo and Edwal LFN are just so, so expensive. Why for what those costs, one could afford to put money in a parking meter!
